Description

Technical Field

[0001] The present invention belongs to the technical field of sewage treatment, and more specifically, relates to a sewage treatment device for water pollution control. Background Art

[0002] Domestic sewage contains a large amount of organic matter, bacteria, etc., which are harmful to the environment. In addition, many parts of sewage are acidic or alkaline. Direct discharge of these acidic or alkaline sewage will cause harm to the environment and aquatic organisms. Therefore, before sewage is directly discharged into the external environment, it is necessary to remove harmful substances and perform acid-base neutralization treatment on the sewage.

[0003] The current sewage treatment equipment for water pollution control still has some shortcomings in actual use:

[0004] 1. Traditional acid-base neutralization treatment equipment usually adopts a simple stirring and mixing method, adding the acid or alkali agent directly into the sewage pool for neutralization reaction. However, this method has problems such as uneven mixing, low reaction efficiency, and incomplete neutralization, making it difficult for the treated sewage to stably meet the discharge standards;

[0005] 2. In the actual use of traditional sewage treatment devices for water pollution control, the pH meter is usually only targeted at a single location, which cannot fully reflect the actual neutralization state of the sewage in the tank, resulting in adjustment lag or error. In addition, the pH meter is immersed in sewage for a long time, and its probe is easily attached and contaminated by impurities in the sewage, resulting in inaccurate test data. Cleaning and maintenance of the pH meter are complicated. Therefore, in view of this, the existing structure and deficiencies are studied and improved to provide a sewage treatment device for water pollution control, in order to achieve the purpose of greater practical value.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the sewage treatment device for water pollution control, multiple mixing plates with different angles are set in the mixing pipe, which can enable the acid or alkali agent and sewage to be preliminarily mixed before entering the neutralization tank. In the neutralization tank, the convex strips on the conical disk disperse the sewage, and the stirring blades stir and mix it. At the same time, the honeycomb-shaped spoiler mesh moves up and down to enhance the turbulence. A multi-stage mixing method is adopted, from preliminary mixing to deep stirring and turbulence, which increases the contact area and mixing uniformity between sewage and chemicals, greatly accelerates the neutralization reaction speed, and improves the efficiency and effect of sewage treatment.

[0019] 2. The pH meter 1 on the connecting pipe of the sewage treatment device for water pollution control monitors the pH value of the sewage entering the device in real time, providing data support for the addition of acid or alkali agents. The pH meter 2 in the neutralization tank can accurately detect the pH value of sewage at different depths in the tank by adjusting the depth of the detection head, and provide real-time feedback on the neutralization status of the sewage to ensure that the treated sewage meets the neutrality standard.

[0020] 3. Multiple pH detectors are equidistantly installed in the accommodating tank on the surface of the drum in the detection shell. They are distributed along the height of the drum and can detect the pH value of sewage at multiple depths in the neutralization tank. Multi-point detection can fully reflect the pH value of the sewage in the neutralization tank, avoiding the possible errors of single-point detection and ensuring the accuracy and reliability of the test results.

[0021] 4. Honeycomb spoiler mesh plate The honeycomb pore structure divides and recombines the sewage, increases the mixing opportunities between different parts of the sewage, helps to break the concentration gradient in the sewage, makes the agent more evenly distributed in the sewage, and ensures that the neutralization reaction is carried out under more uniform conditions. The honeycomb spoiler mesh plate moves up and down under the action of the cam and spring, causing the sewage passing through to have a turbulent effect. The dynamic turbulence effect increases the contact area and time between the sewage and the agent, promotes the neutralization reaction to proceed more fully, helps to improve the quality and efficiency of sewage treatment, and makes the treated sewage closer to the neutral standard.

[0022] 5. The sealing member 1 in the connecting port seals the rotor to prevent the sewage in the neutralization tank from leaking from between the rotor and the inner wall of the connecting port to the cleaning port. The sealing ring inside the detection shell seals the rotating shaft 3. Together with the arc-shaped baffle sealing the cleaning port, a double sealing structure is formed to effectively prevent the sewage in the neutralization tank from leaking, thus ensuring the safety and stability of the sewage treatment device and avoiding secondary pollution to the environment caused by sewage leakage.

[0023] 6. When the pH detector 2 needs to be cleaned, start the motor 2, which can make the drum drive the pH detector 2 to rotate to the cleaning port, making it convenient for the staff to clean. At the same time, the rotation of the arc baffle realizes the opening and closing of the cleaning port, ensuring the convenience and sealing of the cleaning process, facilitating daily maintenance of the detector, ensuring its detection accuracy, and extending the service life of the pH detector 2.

A synchronous wheel three 94 is fixedly installed on the upper rotating shaft three 93. The interior of the rotating shaft three 93 is hollow, and a threading hole is provided in the middle of its upper surface for the wiring harness to pass through the threading hole and connect with the pH detector two 92. The side end of the neutralization tank 1 is installed with a detection shell 6, and the surface of the detection shell 6 is provided with a connecting port 61 that communicates with the inner cavity of the neutralization tank 1. The rotating drum 9 is rotatably installed in the connecting port 61. The surface of the rotating drum 9 is provided with a receiving groove 91, and a plurality of pH detector two 92 are equidistantly installed in the receiving groove 91. The plurality of pH detector two 92 are distributed along the height direction of the rotating drum 9. The plurality of pH detector two 92 are equidistantly installed in the receiving groove 91 provided on the surface of the rotating drum 9 are distributed along the height direction of the rotating drum 9, and can perform pH detection on sewage of multiple different depths in the neutralization tank 1;

[0053] A sealing member 65 for sealing the rotating drum 9 is provided in the communication port 61, a sealing ring for sealing the rotating shaft 3 93 is provided inside the detection shell 6, a cleaning port 62 is provided on the outer surface of the detection shell 6, an arc-shaped groove 64 is provided on the inner wall of the cleaning port 62, an arc-shaped baffle 95 for blocking the cleaning port 62 is slidably installed in the arc-shaped groove 64, a rotating plate 97 is fixedly installed at the bottom of the arc-shaped baffle 95, and the rotating plate 97 is rotatably installed in the detection shell 6, and the inner wall of the arc-shaped groove 64 is provided with a curved baffle for blocking the cleaning port 62.

Together with the arc-shaped baffle 95 sealing the cleaning port 62, a double sealing structure is formed to effectively prevent the sewage in the neutralization tank 1 from leaking, ensuring the safety and stability of the sewage treatment device and avoiding secondary pollution to the environment caused by sewage leakage.

[0054] A fixing block 96 is fixedly mounted on the outer wall of the arc-shaped baffle 95. An avoidance groove 63 adapted to the fixing block 96 is opened on the outer surface of the detection shell 6. The avoidance groove 63 communicates with the arc-shaped groove 64 and the cleaning port 62 to avoid the rotation path of the fixing block 96.

[0055] The upper end of the detection shell 6 is provided with a driving assembly, which includes a second motor 8 and a second rotating shaft 85. The second motor 8 is fixedly mounted on the upper end of the detection shell 6. The output shaft of the detection shell 6 is fixedly connected to a driving shaft 81. A driving gear 82 and a second synchronous wheel 83 are fixedly mounted on the driving shaft 81.

The rotation angle of the rotating drum 9 is 180 degrees, and the rotation angle of the arc baffle 95 is half of the rotation angle of the rotating drum 9, which prevents the arc baffle 95 from rotating through the connecting port 61, thereby preventing sewage from leaking from the penetration and ensuring a stable seal.

[0056] A liquid outlet pipe 11 is installed at the lower part of the side end of the neutralization tank 1, and a spare addition pipe 12 is provided at the upper part of the side end of the neutralization tank 1. If the test data does not meet the standard, an appropriate amount of acid or alkali agent can be added through the spare addition pipe 12 provided at the upper part of the side end of the neutralization tank 1 to further adjust the pH value of the sewage.

[0057] The working principle of this embodiment is as follows:

[0058] Step 1: When using the sewage treatment device, a fixed amount of sewage is first transported to the mixing tube 2 through the connecting pipe 22. The sewage flows into the neutralization tank 1 from the L-tube 23 connected to the middle part of the upper end of the mixing tube 2. The pH meter 29 installed on the connecting pipe 22 monitors the pH value of the sewage in real time. According to the pH value data of the sewage fed back by the pH meter 29, the system accurately inputs a fixed amount of acid or alkaline agent into the mixing tube 2 by controlling the metering pump 27. A plurality of mixing plates 21 are distributed along the axial direction of the mixing tube 2, and there is an angle difference between adjacent mixing plates 21, which promotes the acid or alkaline agent to be fully mixed with the sewage in the mixing tube 2, and then transported to the neutralization tank 1, laying the foundation for a more efficient neutralization reaction in the neutralization tank 1.

[0059] Step 2: The sewage transported to the neutralization tank 1 first falls into the middle of the conical disk 42. At this time, the motor 1 5 is started, and the output shaft of the motor 1 5 drives the drive shaft 51 to rotate. The drive shaft 51 drives the stirring shaft 4 to rotate by meshing with the bevel gear 1 44 and the bevel gear 2 52 on the stirring shaft 4. The rotation of the stirring shaft 4 causes the conical disk 42 and the plurality of stirring blades 41 to rotate together. During the rotation of the conical disk 42, the convex strips 43 evenly distributed on the circumference of the upper end thereof disperse the sewage that falls into it, so that the sewage is more evenly distributed in the neutralization tank 1. At the same time, the stirring blades 41 stir and mix the sewage that falls into the bottom of the inner cavity of the neutralization tank 1, accelerating the sewage to fully contact with the acid or alkali agent preliminarily mixed in the mixing tube 2 and causing a neutralization reaction;

[0060] The third step: the sewage dispersed by the convex strips 43 first passes through the honeycomb spoiler mesh plate 3, and then falls into the neutralization tank 1 to be stirred and mixed by the stirring blades 41. The driving shaft 51 is transmitted to the rotating shaft 7 through the synchronous wheel 153 and the synchronous belt 154. When the driving shaft 51 rotates, it drives the rotating shaft 7 to rotate, and then the cam 71 on the rotating shaft 7 rotates. When the raised portion of the cam 71 contacts the surface of the ball 32 at the bottom end of the ear block 31, an upward force is applied to the ear block 31, so that the honeycomb spoiler mesh plate 3 overcomes the elastic force of the spring 134 and moves upward. When the raised portion of the cam 71 rotates away from the ball 32, under the reset action of the spring 134, the honeycomb spoiler mesh plate 3 moves down and resets. As the rotating shaft 17 and the cam 71 continue to rotate, the honeycomb spoiler mesh plate 3 moves back and forth, further enhancing the spoiler effect of the sewage, so that the sewage is more fully mixed with the acid or alkali agent when passing through the honeycomb spoiler mesh plate 3, which helps to improve the efficiency and effect of the neutralization reaction.

[0061] Step 4: In the detection shell 6 installed at the side end of the neutralization tank 1, multiple pH detection meters 2 92 are equidistantly installed in the accommodating groove 91 opened on the surface of the rotating drum 9, which are distributed along the height direction of the rotating drum 9. The pH value of sewage at multiple depths in the neutralization tank 1 can be detected. The sealing member 1 65 provided in the connecting port 61 seals the rotating drum 9, and the sealing ring provided inside the detection shell 6 seals the rotating shaft 3 93. In addition, the arc-shaped baffle 95 seals the cleaning port 62 to form a double sealing structure, which effectively prevents the sewage in the neutralization tank 1 from leaking out from the cleaning port 62. When the detection data of multiple pH detection meters 2 92 all meet the discharge standards, the liquid outlet pipe 11 is opened, and the sewage that meets the standards is discharged from the liquid outlet pipe 11. If the detection data does not meet the standards, an appropriate amount of acid or alkali agent can be added through the spare adding pipe 12 provided on the upper part of the side end of the neutralization tank 1 to further adjust the pH value of the sewage.

[0062] Step 5: When it is necessary to clean the probe on the pH detector 2 92, start the motor 2 8, the output shaft of the motor 2 8 drives the driving shaft 81 to rotate, and the driving gear 82 and the synchronous wheel 2 83 fixedly installed on the driving shaft 81 rotate accordingly. When the driving gear 82 rotates, it drives the driven gear 84 engaged with it to rotate, and the driven gear 84 rotates to drive the rotating shaft 2 85 to rotate. The rotating shaft 2 85 is connected to the arc baffle 95 through the connecting rod 86, thereby driving the arc baffle 95 to rotate with the rotating shaft 3 93 as the axis. When the arc baffle 95 rotates, it retracts into the arc groove 64. At this time, the arc baffle 95 no longer covers the cleaning At the same time, the synchronous wheel 2 83 rotates through the synchronous belt 2 87 to drive the synchronous wheel 3 94 and the rotating shaft 3 93 to rotate, so that the rotating drum 9 rotates with the rotating shaft 3 93 as the axis. Since the encoder is installed on the output shaft of the motor 2 8, the rotating drum 9 can be accurately controlled to rotate one hundred and eighty degrees, thereby driving the pH detector 2 92 to rotate to face outward. At this time, multiple pH detectors 2 92 are located at the cleaning port 62, which is convenient for the staff to clean them. After cleaning is completed, the motor 2 8 is started again to reset the rotating drum 9 and the arc baffle 95, restore the sealing state of the detection shell 6, and ensure that the sewage treatment device continues to operate normally.
